.Y use] l 4 claims. This invention-has for its object to realize a 4roller skate having steering and braking devicesand permitting a parallel running of the skates similar to that known by ski-running.

The invention will be described with'reference,

to the accompanying drawings, in which:

Figure 1 is a planl view of a roller skate; Figure 2, a side elevation and Figure 3. a iront view of thesame: Figure 4,` a partial front view of the steering device after action; Figure 5, a side elevation of the roller skate in a modied form: Figure 6. a. front view oi' the same: Figure' '1. a

l Referring to the drawings, the frame l oi the roller skate vis preferably made of sheet metal, which is bent to form two branches la, lb, supported by the axle 2 of the back wheel 3, which is 2g provided with rubber tyres. The frame I may be made lalso of a slight cast metal. The back wheel 3 is arranged by means of a suitable known device so as to be prevented from running backwards, but only forwards-fior' ex-A ample by means of a ratchet wheel la secured to the back wheel and acted on by a spring ieontrolled pawl Ib. 4(.lrossbarsl arenttedtothefrontpartoithe `freine i and they carry a supporting plate-l oi so conventional design to which the boot is secured 4 by means of wellknown fastening devices. such as i clamps ia.

1f the sksterwisnes to change the direction of his run,v he presses the plate 5 to one side causing the frame i to pivot laterally around the rod lo towardsthe desired side thereby causing the toothed segment II to rotate the toothed segment `5 Il, for displacing the steering axle Il in the corresponding direction. Springs I'I are arranged between the bearing Il and the forked end I6 of the frame rod I6 in order to limit themotion of the axle I3 and to assist in returning the frame I l0 to its normal horizontal condition.

'For brs'sing, the'skater presses down with the heel the back portion of the plate l, causing the latter to pivot around the .pin 6. By this movement a tractlve eilort lon the brake bands 8 is 15 produced so as to bring the latter into contact.

It will also be noted that the toothed segments Il, Il of the steering device may be replaced by a forked extension termina ing arms Il and lla disposed so as to bearagainst and actuate the steering axle I3 on one side or the other of the vertical pin l2, according as the y frame i is inclined by the skater towards the right or the left.v (Figs. 5, 6.) f 25 Having thus described my present invention. what I now claim and desire to secure by letters Patent is:
